'BUcHhNn, "or sirnacusn, NEW Yoan HEADLIVGHT.

Sl'jojall 'whom z't'rr'z/ag/concern: y. l, -1 j i it known'that I, FRANKBUCHANAN a citizen of the United States,l andga resident of'Syracuse, yin the county of Onondagak and ii State of Nevv York, have Iinventedalcertain fnew vand useful Headlight, of which thefoli, `iowin'g'is aspecification. t o invention relates to head lights, have -xing incandescent electric lamps and it perl() flamp axially of the 'light ifecusing means or j reiectorthereof, and the invention consists in the combinations and constructions hereinafter'set forth and claimed.` g i In describing this invention reference is 1 had the accompanying drawings in which parts in all the views. s @Figure 1 isa front elevation of Yone form of lhead light embodying my invention, the door offthe case being open, 'and'th lamp being removed from 4the socket. Fig."2 is va sectional view, partly in elevation, on the plane of line A--Aj Fig.' 1,'the door being shown as closed and the lamp being illus- --trated asinserted into yitssocket. yEig. 3v is an.' enlarged sectional view 'of the support for the lamp socket and contiguous parts. F ig. 4 is a sectional view 'on the plane' 'of '1 iI1`e.,B-B, F ig;y 3, the wall of the case bef-in omitted. v his head lighty comprises, generally, a case, a light focusing means`or reflector in the case, an incandescentl electric lamp withi in the reflcctonasocket for'the lamp, and -xneans p for supporting and adjusting the socket comprising a movable carriage-a sta- 4 tionaryl frame for 'supporting the carriage,

and members associated with'the frame for inoving the carriageand adjusting the lamp axially of the reflector. The members for moving the carriage andtherebyadjustmg lthe lamp axially of the'reflecton'are preferably arrangedeccentrc to the axis of the reflectorand lamp socket andV extendv parallel thereto, and an operating partis arranged concentric with such axis and connected to said members', v e e, y

`like characters designate corresponding 'patented aug, it', 1915, serial Nolcwea of the axis of the reflector 4; and is the socket orl support for `the lamp, said socket being. hereqshown as 4arranged coaxially with the reflector 4 so that the lamp 5 is held in horizontal position at the axis of the reector 5 is the incandescent electric lamp. adjust- 7 is the carriage for the socket 6, -saidcar-il y riage. being arranged at the rear ofthe reie'ctor 4 and havingv a substantially central -opening 8 by means of which the socket 6v l may be secured thereto by any suitable vfasteni'ng means. vThe plurality of members for moving the carriage comprise preferably three screws 9spaced equidistant apart' and arranged eccentric to, and parallelv to, the

ment in any suitable manner and extend 'axis of the reflector 4. Said screws are supported and held from endwise move-` through threaded eyes or openings 10 in the socket carriage 7. As here illustrated the screws 9 are formed with axles 11 at their;

ends which are journaled in openings in vsuitable supporting elements" as rear and- :front plates .12 and 13, which are arranged at the rear of the reflector 4 and, with connecting tie rods 14 constitute the stationary frame for supporting. the carriage 7, the rear plate 12 being at the rear of thecarriage'' andengaging and being securedto the rear wall 3, and the front plate 13 being annular in form and supported in front of said carriage by the rods 14 projecting from the element 12 and said plate 13 being provided with a central opening or passage vcoaxial with the opening'in the rear end of the' reflector. Said rods extendl through openings in the carriage 7 and have reduced threaded ends 15 extending through openings in the platev 13 and receiving suitable nuts 16 which turn' against the 'outer face of said plate 13. The rods 14 areralso formed with threaded reduced ends 17 which extend through openings in the plate l2 and through the rear wall 3 of the case, andnuts 18 turn on such projecting ends .against ythe wall 3 for securing thel plate 12 and parts carried thereby in position. The plates-12 and 13, rods 14,screws 9 and carriage 7 constitute supporting. and adjusting means for the lamp socket 6,-and' said means are supported independently of the reflector in order that` said reflector may be free yfrom all strains incidental to the' support and adjustment' ci the lamp. The screws 9 are turned in order to move the carriage v7 'and al@ Socket 6 carried phreby axiaiiy of as reiiector 4, by a gear 19 mounted coa'x'iallyv with the socket-6 reflector Lin rear of 'the' reector and engaged with pinionsg20 mounted on and preferably, formed integral-.f

-^ with the screws 9. Thev gear 19 is ,provided hand engaging part 22' mounted on the threaded outer end Iofthe stud 21. Obviouslyby turning the part 22 the motion4 thereof will be transmitted by the gear 19, inions 20 and screws 9 to the carriage 7.

= The electrical connections for the terminals of the lamp socket may be made in any suitable manner and as such connections form no part of this invention, description thereof is unnecessary.

Owing to the arrangement of the meansfor adjusting the lamp 5 axially of the reflectors, no holding vmeans is required to hold the lamp in its adjusted position, and owing to the use of a plurality of screws 9,

binding of the carriage is prevented.
